          A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO.

          I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?

            Yeah, sorry for the confusion. I put the tag on all the pages (Original and Duplicate). I sent you a PM with another good article on Rel canonical tag

                Generally agree, although I'd just add that Robots.txt also isn't so great at removing content that's already been indexed (it's better at prevention). So, I find that it's not just not ideal - it sometimes doesn't even work in these cases.

                Rel-canonical is generally a good bet, and it should go on the duplicate (you can actually put it on both, although it's not necessary).

                    per google webmaster tools:

                    If Google knows that these pages have the same content, we may index only one version for our search results. Our algorithms select the page we think best answers the user's query. Now, however, users can specify a canonical page to search engines by adding a element with the attribute rel="canonical" to the section of the non-canonical version of the page. Adding this link and attribute lets site owners identify sets of identical content and suggest to Google: "Of all these pages with identical content, this page is the most useful. Please prioritize it in search results."

                      Thanks Kyle. Anthony had a similar view on using the rel canonical tag. I'm just curious about adding it to both the original page or duplicate page? Or both?

                      Thanks,

                      Greg

                        Anthony, Thanks for your response. See Kyle, he also felt using the rel canonical tag was the best thing to do. However he seemed to think you'd put it on the original page - the one you want to rank for. And you're suggesting putting on the duplicate page. Should it be added to both while specifying which page is the 'original'?

                        Thanks!

                          I'm not sure I understand why the site owner seems to think that the duplicate content is necessary?

                          If I was in your situation I would be trying to convince the client to remove the duplicate content from their site, rather than trying to find a way around it.

                          If the information is difficult to find then this may be due to a problem with the site architecture. If the site does not flow well enough for visitors to find the information they need, then perhaps a site redesign is necessary.

                            Well, the answer would be yes and no. A robots.txt file would stop the bots from indexing the page, but links from other pages in site to that non indexed page could therefor make it crawlable and then indexed. AS posted in google webmaster tools here:

                            "You need a robots.txt file only if your site includes content that you don't want search engines to index. If you want search engines to index everything in your site, you don't need a robots.txt file (not even an empty one).

                            While Google won't crawl or index the content of pages blocked by robots.txt, we may still index the URLs if we find them on other pages on the web. As a result, the URL of the page and, potentially, other publicly available information such as anchor text in links to the site, or the title from the Open Directory Project (www.dmoz.org), can appear in Google search results."

                            I think the best way to avoid any conflict is applying the rel="canonical"  tag to each duplicate page that you don't want indexed.

                            You can find more info on rel canonical here

                            Hope this helps out some.

                              The best way would be to use the Rel canonical tag

                              On the page you would like to rank for put the Rel canonical tag in

                              This lets google know that this is the original page.

                              Check out this link posted by Rand about the Rel canonical tag [http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps](http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps)

                                Should I use noindex or robots to remove pages from the Google index?

                                I have a Magento site and just realized we have about 800 review pages indexed. The /review directory is disallowed in robots.txt but the pages are still indexed. From my understanding robots means it will not crawl the pages BUT if the pages are still indexed if they are linked from somewhere else. I can add the noindex tag to the review pages but they wont be crawled. https://www.seroundtable.com/google-do-not-use-noindex-in-robots-txt-20873.html Should I remove the robots.txt and add the noindex? Or just add the noindex to what I already have?

                                Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google

                                I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

                                Hi, I'm not too sure what to do about this or what to think of it. This magically appeared in my companies robots.txt file (literally magically appeared/text is below) User-agent: Baiduspider
                                User-agent: Baiduspider-video

                                Should I use meta noindex and robots.txt disallow?

                                Hi, we have an alternate "list view" version of every one of our search results pages The list view has its own URL, indicated by a URL parameter I'm concerned about wasting our crawl budget on all these list view pages, which effectively doubles the amount of pages that need crawling When they were first launched, I had the noindex meta tag be placed on all list view pages, but I'm concerned that they are still being crawled Should I therefore go ahead and also apply a robots.txt disallow on that parameter to ensure that no crawling occurs? Or, will Googlebot/Bingbot also stop crawling that page over time? I assume that noindex still means "crawl"... Thanks 🙂

                                Do you add 404 page into robot file or just add no index tag?

                                Hi, got different opinion on this so i wanted to double check with your comment is. We've got /404.html page and I was wondering if you would add this page to robot text so it wouldn't be indexed or would you just add no index tag? What would be the best approach? Thanks!

                                Google somehow has indexed a page of mine without the .html extension.  so they indexed  www.samplepage.com/page, so I am showing duplicate content because Google also see's  www.samplepage.com/page.html   How can I force google or bing or whoever to only index and see the page including the .html extension?  I know people are saying not to use the file extension on pages, but I want to, so please anybody...HELP!!!

                                Using 2 wildcards in the robots.txt file

                                I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it?  So something like /_Q1.  Will that pickup and block every  URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1.  So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on?

                                How to resolve Duplicate Page Content issue for root domain & index.html?

                                SEOMoz returns a Duplicate Page Content error for a website's index page, with both domain.com and domain.com/index.html isted seperately. We had a rewrite in the htacess file, but for some reason this has not had an impact and we have since removed it. What's the best way (in an HTML website) to ensure all index.html links are automatically redirected to the root domain and these aren't seen as two separate pages?
